Muscle thickness, measured by ultrasonography, has been investigated for nutritional
assessment in older adults, however the associations between muscle ultrasound parameters in the
lower limb and nutritional status have not been studied. The aim of this study was to investigate
the relationship between muscle thickness echo intensity (EI), and nutritional status in home care
residents. A cross sectional study was conducted involving 19 older adults from a home care in
Malaga (Spain). We evaluated lower leg muscles by ultrasound, anthropometric data, physical
function (measured by gait speed and the Short Physical Performance Battery), strength (handgrip and
knee extensors strength) and nutritional status across the Mini-Nutritional Assessment Short-Form
(MNA-SF). We found that muscle thickness assessed by ultrasonography independently predicts
nutritional status by MNA-SF and after adjusting for handgrip strength or age and sex. As secondary
findings, we found relations between strength, functional capacity and the MNA-SF test. These
results suggest that lower leg muscle ultrasound parameters could be used as a low-cost objective
method for muscle evaluation in nutritional assessment in older adults.
